Shares here are read over the models both editions asked, so they can differ by a point or two from the standing above, which counts every model in this edition.
The floor is 11 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one is noise, and both are shown. Movement is read over the twelve models both editions asked; GPT-6 Luna, Muse Glimmer 30B joined this edition and are in the standing but not yet in the comparison.

What the models said for it
Verbatim evidence the judge attached to positive labels.
“I'd pick LangSmith as the observability layer” GPT-5.4 mini · LLM gateways · paraphrase prompt · first choice
“Heavy LangChain use: LangSmith (seamless evals/monitoring). ... Routing not as native/built-in.” Grok 4.20 · LLM gateways · paraphrase prompt · alternative
“LangSmith is the industry standard... Downside: Tightly coupled with the LangChain ecosystem.” Qwen 3.7 Flash · LLM gateways · paraphrase prompt · alternative
And against it
Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.
“What I'd avoid for your use case ... LangSmith \u2014 Proprietary, tightly coupled to LangChain, and expensive at scale” DeepSeek V4 Flash · LLM gateways · paraphrase prompt · hard negative
“$39/seat/month adds up quickly for teams” Kimi K2 · LLM gateways · paraphrase prompt · hard negative

A head-to-head page exists where both products are among a category's top eight. The other rows are the same fact without a page behind them, so they link to the product instead.
What carried it into the answer
The sites and pages cited by the answers that named LangSmith. A fact about retrieval, not a lever on the model.
Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 14 of the 17 answers that named LangSmith and are not a share of its labels.

How it is countedHide how it is counted
Every page langchain.com exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person. Read September 29, 2026.
Names read as LangSmith
What the judge wrote, as written, with how often. The vendor table decides that these count as LangSmith; a claim can dispute any of them.

Is this your product?
Claim this page
Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when LangSmith's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as LangSmith, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.
What a new claim receivesHide what a new claim receives
A new claim receives the current edition's vendor brief for LangSmith by email, built from the raw record of the edition. It shows:
- where LangSmith is named, by buyer and by framing, and which cells hold its first choices;
- the claims the models make when they name it, ranked, with the strongest and the weakest quoted;
- its vocabulary against the segment leader's, and the pages the models cited;
- who was chosen in the answers that did not name LangSmith, and every reason the record gives;
- a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
- one page of published figures cleared to show a buyer.
